Abstract

This study aimed to know the fermentation profile of yellow sweet potato (total lactic acid bacteria, total non-lactic acid bacteria, total lactic acid, pH, total exopolysaccharides, and morphology changing on starch granules) using Leuconostoc mesenteroides as a starter. The sample's withdrawal was performed at 0, 24, 48, and 72 hours. The results showed that during 72 hours fermentation time, there was a linearly decreased of pH (minimum at pH 3.80), a linearly increased of total lactic acid (0.0023% /h), reducing sugars (0.26 mg/ml/h), crude exopolysaccharides (EPS) (0.017 g/l/h), and total Lactic Acid Bacteria (LAB) (maximum at log 8.40 cfu/ml), as well as a decreased of non-Lactic Acid Bacteria. Leuconostoc mesenteroides had significant effect on granule of yellow sweet potato. There was an alteration of starch granules at the end of fermentation time (at 72 hours).
